Asymmetric drift in MaNGA: Mass and radially-dependent stratification rates in galaxy disks
Matthew A. Bershady, Kyle B. Westfall, Shravan Shetty +5
We measure the age-velocity relationship from the lag between ionized gas and stellar tangential speeds in ~500 nearby disk galaxies from MaNGA in SDSS-IV. Selected galaxies are ki…
SDSS-IV MaNGA: Calibration of astrophysical line-widths in the Hα region using HexPak observations
Sabyasachi Chattopadhyay, Matthew A. Bershady, David R. Law +7
We have re-observed 40 low-inclination, star-forming galaxies from the MaNGA survey ($\upsigma\sim65$~\kms) at 6.5 times higher spectral resolution ($\upsigma\sim10$…
SDSS-IV MaNGA: Modeling the Spectral Line Spread Function to Sub-Percent Accuracy
David R. Law, Kyle B. Westfall, Matthew A. Bershady +10
The SDSS-IV Mapping Nearby Galaxies at APO (MaNGA) program has been operating from 2014-2020, and has now observed a sample of 9,269 galaxies in the low redshift universe (z ~ 0.05…
Stellar Population Synthesis with Distinct Kinematics: Multi-Age Asymmetric Drift in SDSS-IV MaNGA Galaxies
Shravan Shetty, Matthew A. Bershady, Kyle B. Westfall +5
We present the first asymmetric drift (AD) measurements for unresolved stellar populations of different characteristic ages above and below 1.5 Gyr. These measurements sample the a…
A Precise Benchmark for Cluster Scaling Relations: Fundamental Plane, Mass Plane and IMF in the Coma Cluster from Dynamical Models
Shravan Shetty, Michele Cappellari, Richard M. McDermid +4
We study a sample of 148 early-type galaxies in the Coma cluster using SDSS photometry and spectra, and calibrate our results using detailed dynamical models for a subset of these…
The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Emission-Line Modeling
Francesco Belfiore, Kyle B. Westfall, Adam Schaefer +12
SDSS-IV MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is the largest integral-field spectroscopy survey to date, aiming to observe a statistically representative samp…
